Cross-checking the symmetry energy at high densities

Abstract

By considering both the effects of the nucleon-nucleon short-range correlations and the isospin-dependent in-medium inelastic baryon-baryon scattering cross section in the transport model, two unrelated Au + Au experimental measurements at 400 MeV/nucleon beam energy are simultaneously analyzed, and a mildly soft symmetry energy ($L({\ensuremath{\rho}}_{0})=37$ MeV) at supra-saturation densities is obtained. This result is compatible with recent result [Phys. Rev. C 92, 064304 (2015)] shown by comparing the available data on the electric dipole polarizability with the theoretical predictions.
